Cross-section Morphology of the Scratch-Induced Cracks in Soda-Lime-Silica Glass
Scratch-induced cracking is a serious problem for the use of glass products. At the scratch process, both median (vertical to the glass surface) and lateral (horizontal to the glass surface) cracks are formed. In this study, morphology of the scratch-induced cracks in a commercial soda-lime-silica glass was investigated by the scanning electron microscopy for the specimen broken across the scra...
متن کاملQuantitative image analysis for evaluating the abrasion resistance of nanoporous silica films on glass.
The abrasion resistance of coated glass surfaces is an important parameter for judging lifetime performance, but practical testing procedures remain overly simplistic and do often not allow for direct conclusions on real-world degradation. Here, we combine quantitative two-dimensional image analysis and mechanical abrasion into a facile tool for probing the abrasion resistance of anti-reflectiv...
متن کاملPlasticity-induced structural anisotropy of silica glass.
Amorphous silica density at ambient pressure is known to depend on thermal history (through the quenching rate) but also, at room temperature, on the maximum pressure applied in the past. Here we show that beyond density, a mechanical loading can endow the structure with an orientational order. Molecular dynamics simulations show evidence that amorphous silica develops a permanent anisotropic s...

15 صفحه اولThe Effect of Different Periods of Enamel Microabrasion on the Microleakage of Class V Glass-Ionomer Restorations
Objective: Removal of enamel superficial layer during microabrasion treatments may adversely affect sealing ability of the restorative materials. The aim of this study was to measure the effect of different periods of enamel microabrasion on the microleakage of class V glass-ionomer restorations. Methods: This in vitro experimental study was conducted on 96 Class V cavities which had been pr...
